Pycnodonte Oyster Fossil

This fossil is an extinct oyster from the family Gryphaeidae. It is called Pycnodonte newberyii from the Cretaceous Period and the Turonian Age. The fossil was found in Utah probably near the Tununk layer of the Mancos Shale near Dakota Sandstone. Might also be known as the "Devil's Toenail."
